To all whom t may concern.'

Beitknown that I, JAMES Gr. GRAI'NGER, a citizen of the UnitedStates, residirrgat 'Centralia, in the county of Lewis and State of lVashingt-on, have vinvented ya LnQW and vuseful FalletSetter-Gage, of whih theollowing isa specication.

This inventionhas yreferencefto gages for properlyfsettingthe jewels in pallets off different makes of watches, and its object 'is to provide a gage wherebythe jewels, `whether already present-'in the pallets 'or replacing broken or lost jewels, may be accurately 'set `whether or not the watch movement be present.

In accordance with the invention, .,the'reiis provided a body member, which may be in 'tailed description taken in lconnection with the accom anying drawing -formingfpart of this speci cation, with the understanding,

-howeventhat the invention is not confined to any strict conformity withtlie' showing of the drawing but may be changed and fmodiied so long as such changes and lmodifications mark no material departure fromthe salientlfeatures of the invention as expressed in the appended claims.

In the drawing Figure 1 -is a face view of a pallet gage 'with va pallet in positionthereon.

Fig. 2 is a section on the iline -2^2 of Fig. 3 'is a Vface view of 'the opposite rside of the gage with the parts in somewhat differcntposition from that shown in Fig. l.

Fig. 4 isa view of the slide vremoved from the body of thegage. j

Fig. 5 is a section on the line 5-,5 'of Fig. 3.

Fig. 6 is a-detail view showingthe operation of the gage with respect to a different form ofpa'llet 4from'fthat shown inF-ig. 1.

Referring to the drawing there is shown :elongated rectangular piatte -1 `cornistitut- -vmgf the had? ni fthe gege,

form 'of 3 body member not being obligatory but at the same time providing acon'venient -body gmember for the gage.

Mounted yon the body'mern'ber isa slide 2 conveniently Vformed of `face Istrips g3, 4 `l`and end stripsl. The `(face strips 3 and'tezXtend across'the respective faces 'ofltheplat'ell and have l"edge portions -1'6 fat asl-iight angle-to the wid-th of the/plate'. :Inthe strips" 3 l'and T4' are recesses 7 to accommodate certain parts cofthe pallets. 1" v The body-line ber or platell i's'alsofpro- Y-vided with `Vanothe'rfslide designed to'serve "as a `fol-lower for the-slide-2T The slide l8 Iis `lprovided-inthey edge toward 'the slide -2 with -recesses 9.v

The body member or plate 1 wise of the; bodymember yand in ithe particular showing oftle -drawingfthere are two'oi spaced from the edgesvoff-the'body member 1 and from eachother. The invention isA not conined to any suchparticular arrangement but with a gage of moderat-e size, say about three and onehalf inches'ilo'ng and one inch wide, practically all makes of-palletsm'ay be accommodated. v

In Figs. 1 'and 2 vthere is shownva pallet 11 with` jewels 12, a fork 1B jat-one-endland an arm 14 -at the other gend,this being a yform of pallet `employed in `certain iwatches. In Fig. 6 there lis shownanother fornifof pallet 15 v`having jewels 16 with 'a ork'17 arranged has rows of d l holes or perforations y10 extending lengthsuch rows of holes' about vequi-dista'ntl'y.-`

at --right angles to the -larrangement'shownin 'the -pallet"11. Each Vpallet has an l'arbor 18 and the holes 10 in fthe rows 'of holes vvare Iso arranged as'to'receive'the arbor'sorlstaffs 18 of different 'makes of pallets. Y Y

The holes 'vor receptacles 10 are t'arranged in rows llengthwise ofthe plate 1 and eX-' tending crosswise of the lplate soV as to each intersect ahole 10 are lines 19, the longitudinal rows of fholes' being, joined "by 'other lines V20. Moreover,the en d straps orl guide bars `5 which engage :and move falon'g the -edges of the plate 1 andare of greater length than the width .of the 'strips' 31 andV @have Yeach a mark or Iline 21 to `register with :any

one offthe 'lines 19. l The plate .1 is provided with symbols, Vw'ords,letters or numbers :related to the holes 10 to designate the holes to vguide the workman with respectto theloarticular holes to Ybe 'chosen for theA particular make of 'watch snee plaeathearher anstatt-@fthe chosen pallet therein. Then the follower slide 8 is moved, in the case of a staff 11, so that the lever end 14 is'seated in a recess 9 with the fork 13 alined with the line 20 and located in a proper recess, or the pallet 15 has its fork 17 extended along a proper line 19. Then the slide 2 is moved toward the pallet 11 until the proper line 21 on the adj acent side bar 5 alines with the same line 19 that traverses the hole 10 in which the arbor 18 is lodged.

If the jewels 12 or 16, as the case may be, are properly set, then they will both just touch of the edge 6 of the bar or strip 3 or 4. If, however, these jewels be improperly set then one or the other or neither may be touched by the edge 6 of the slide 2 when the slide is properly positioned with relation to the chosen line 19, showing the necessity of adjustment of the ewels. If one or the other or both of the jewels be too long then the cement holding the jewel or jewels in the pallet must be softened and the jewel be properly adjusted. If one or both jewels be broken and i-t be desired to replace them the slide 2 and, in the case of the pallet 11, the pallet and follower 8 must be properly adjusted, or in the case of the pallet 15, said pallet be properly adjusted, and then the jewels may be inserted and located and then cemented in the pallet.

These operations may be performed in a minimum time with the assurance that, having the parts properly set, the jewels are located and secured in place with absolute certainty of accuracy. It is not material that the 'watch movement be present since the gage contains infomation apprising the workman of the catalogue number and model and other information, such as the class of the pallet and watch movement, thus permitting the workman to properly set the gage and thereby be sure that the jewels will be properly set for the movement to which the pallet is to be applied, all guess-work and special fitting being eliminated.

Suppose, by `way of example, that a watchmaker receives a pallet without a jewel in it and without lthe movement but receives a description of the watch it belongs to. The jewels are readily set and the pallet may be returned to be placed in the watch movement which it will then fit exactly.

Heretofore, the matching and setting of the jewels in pallets have given watchmakers the most trouble, the pallet being a vital part ofthe watch, but with the gage of the invention such operation is performed expeditiously and with the assurance that the matching and setting is correct even though the work be done in the absence of the watch movement.

What is claimed is 1. A pallet setter gage comprising a 'body portion ,with perforations to receive the bor or staff of the pallet, and a slide movable along the body member and provided with an indi-cation for positioning the slide with respect to a chosen perforation, said slide having a portion constituting a shoulder for abutment by the jewels of the pallet when its arbor is in a chosen perforation.

2. A pallet setter gage comprising an elongated plate with a series of perforations extended lengthwise of the plate to receive the pallet arbor or staff, said plate having indicating lines each extending from a perforation toward the edge portion of the plate, and a slide mounted o-n the plate to move lengthwise thereof and having an indication for positioning the slide with respect to a line leading from a chosen perforation, said slide having a portion constituting a shoulder for abutment by the jewels of a pallet when its arbor is in a chosen perforation and the plate is positioned with respect to said perforation.

3. A pallet setter gage comprising a plate with a series of perforations therein for receiving the arbors or staffs of pallets, and a slide movable along the plate into definite relation to lchosen ones of the perforations with a portion of the slide constituting a shoulder to be abutted by the jewels when the latter are properly set in the pallet.

4. Apallet setter gage comprising an elongated plate with longitudinally extended rows of perforations therein, a slide mounted on the plate to move lengthwise thereof and having shoulders extending erosswise of the plate in slanting relation to the line of travel of the slide, and means for positioning the slide |with relation to any chosen perforations, said perfor-ations constituting receptacles for the arbors or staffs of the pallets and the slanting shoulders constituting abutments for the pallet jewels whereby toposition the jewels in the-pallets.

5. `A pallet setter gage comprising an elongated plate with longitudinally extended rows of perforations therein, a slide mounted on the plate to move lengthwise thereof and having shoulders extending crosswise of the plate in slanting relation to the line of travel of the slide, and means for positioning the slide with relation to any chosen perforations, said perforations constituting receptacles for the arbors or staffs of the pallets and the sla-nting shoulders constituting abutments for the pallet jewels whereby to position the jewels in the pallets, and the means for positioning the slide with relation to lchosen perforations comprising markings on the slide and plate with the markings on the plate intersecting the respective perforations.

6. A pallet setter gage comprising an elongated plate with serially arranged perforations therethrough for receiving the arbors or staffs of pallets, a slide on the plate mov- Cil a'ble lengthwise of the series of perforations In testimony that I claim the foregoing into determined relation to said perforaas my own, I have hereto :Llixed my signations, and a, follower on and movable along ture.
